White Rabbit Mezzanine — hardware overview

OEM timing module — sub-nanosecond White Rabbit sync for system integrators.

5 min read

The White Rabbit Mezzanine is an OEM-focused timing module for integrators who need to embed deterministic, phase-aligned timing into distributed systems. It can drive up to four SFP cages on the host's carrier board, alongside low-jitter local outputs and host-accessible telemetry, to extend and distribute ultra-precise synchronisation across complex environments — and plugs into host systems via a 30-pin × 4-row GPIO connector with USB-C management.
